Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of electric physiological electrode conduit.
Background technology
Electricity physiological electrode conduit (hereinafter to be referred as electrode catheter) is the electricity physiological signal that is used to write down each position in the heart, and heart is carried out electricity irritation, carries out the crux parts of the electric physiology mapping of heart disease.Its method is at first puncture femoral vein blood vessel or internal jugular vein blood vessel, lumen of vessels is delivered to diverse location in the chambers of the heart with electrode catheter in the radioscopy lower edge, heart is carried out electrophysiologic study, bring out and diagnose various arrhythmia, clear and definite ARR origin focus is for radiofrequency ablation therapy provides necessary foundation.This inspection and Therapeutic Method had both avoided patient to open the hardship of breast, can treat arrhythmia again, seldom caused severe complication, and the wide model that obtains is clinically at home and abroad used.
From nineteen sixty after the first patient's heart records His bundle electrogram, clinical cardiac electrophysiology just has been born.The important symbol that forms this subject is through vein electrode to be positioned over different cardias with the core, writes down the exciting signal of partial electrocardio and artificial electrical stimulation is reached cardiac muscle.Because used just top is with the hollow cardiac catheter of electrode, at first to His bundle electrogram to be recorded as power low, conduit need be surveyed for a long time repeatedly at the position, atrial septum.Obviously, the electrode catheter technology of the intracardiac signal of telecommunication of this record is very immature, and poor repeatability can't routine be used for clinical.Began to adopt far-end to be 6 utmost point electrode catheters of J type bending in 1969, can be reliably and record the signal of telecommunication of heart different parts safely, for road has been laid in the fast development of subsequently cardiac electrophysiology.Especially, the electrode catheter technology of record His bundle electrogram is widely used in studying the chamber conduction under various physiology and the pathological condition, the chamber and the intraventricular block of diagnosis different parts, observe the effect of medicine, also greatly improved the diagnostic level of electrocardiogram simultaneously auriculoventricular block to the chamber conduction.Almost simultaneously, utilize the inspection technology (cardiac procedure electricity irritation) of electrode catheter conduction artificial electrical stimulation, and combine, caused the huge leap forward of clinical cardiac electrophysiology with the graph of heart recording technique.Write down the electrocardio-activity of various spontaneous physiology or pathological state by early stage passive type, develop into and to bring out or to simulate various ARR active research methoies, formed the methodology that cardiac electrophysiology is checked.The electrophysiologic study method that adopts the kind electrode conduit to get involved, not only can bring out and stop most tachy-arrhythmia repeatedly, and can measure the various refractory stages of atrium, atrioventricular node, Xi Shi bundle, Purkinje fiber and ventricle, observe and understand the effect of medicine these electric-physiology parameters.Thereupon, for different parts record electrical activity and granting electricity irritation at heart, the electrode catheter quantity that is placed in the chambers of the heart constantly increases, and has formed correctly to diagnose endocardial catheter mapping technology supraventricular and ventricular tachycardia mechanism and origin focus.
In more than 30 year of past,,, developed the electrode catheter of variform and function for some special diagnostic purpose or at specific anatomical cardiac position along with clinical cardiac electrophysiology develops into " treatment " ARR process from " research ".For example: the electrodeplate of electrode catheter is from 2 best, 24 utmost points, the electrode catheter of different poles spacing or group spacing, the electrode catheter of different section bendings far away or camber, the controlled electrode catheter of section far away, the crossed electrode conduit of special record bypass current potential, the energy facility is exclusively used in 10 utmost point electrode catheters of mapping coronary sinus vein, the pulmonary venous controllable electrodes conduit of ring-type mapping along the CT or the Halo electrode catheter of right room circle's ridge or tricuspid annulus placement.In addition, the blue electrode catheter of 64 polar nets that three-dimensional mapping is used has also appearred.
At present, domestic employed clinically electrode catheter is external conduit company and makes, and is mainly Cordis company, Daig company, Bard company and IBI company.The formation of electrode catheter comprises two parts, the one, and far-end has the conduit of varying number electrode, and the 2nd, the external prolongation cable of connection physiograph.Because of needing intravascular, electrode catheter is placed into the different parts of heart, bipolar or the one pole signal of telecommunication in the decapacitation reliable recording chambers of the heart, simultaneously external electricity irritation impulsion is reached outside the intracardiac basic function, also should possess good operating characteristics, comprise compliance, slickness, plasticity, propelling movement or return removing property and rotary torsion, safety comprises the stretching resistance of anticoagulant, electrode catheter on electrode catheter surface and integrity, to the mechanical stimulus of blood vessel and cardiac muscle etc.
At present general clinically electrode catheter is a multipolar electrode catheter, specifically by the conduit of a macromolecular material and distal end of catheter the platinum electrode that quantity do not wait is housed and forms.We find in clinical practice, and the safety for guarantee that electrode catheter is operated in the chambers of the heart requires conduit that enough flexibilities will be arranged; For guaranteeing that conduit has enough propelling movements and moment of torsion, require conduit that enough hardness will be arranged; For delivering to different parts in the heart, head end need give and curve definite shape.The far-end that the near-end that the clinicist operates electrode catheter will curve definite shape inserts in the heart different local.Clinical used conduit is all softer for guaranteeing processing safety at present, is 65-120 centimetre and conduit is long, and actual clinical Chinese physician needs the repeatable operation electrode catheter, electrode catheter could be sent into the heart appointed part.Prolong operating time like this, increased the RADI of X ray patient and surgical doctor.
